ZyAIR B-500 Wireless Access Point User’s Guide Chapter 14 SNMP Configuration This chapter explains SNMP Configuration menu 22. 14.1 About SNMP Simple Network Management Protocol is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. Your ZyAIR supports SNMP agent functionality, which allows a manager station to manage and monitor the ZyAIR through the network. The ZyAIR supports SNMP version one (SNMPv1) and version two c (SNMPv2c).
ZyAIR B-500 Wireless Access Point User’s Guide An agent is a management software module that resides in a managed device (the ZyAIR). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices.

ZyAIR B-500 Wireless Access Point User’s Guide Appendix D Wireless LAN and IEEE 802.11 A wireless LAN (WLAN) provides a flexible data communications system that you can use to access various services (navigating the Internet, email, printer services, etc.) without the use of a cabled connection. In effect a wireless LAN environment provides you the freedom to stay connected to the network while roaming around in the coverage area. WLAN is not available on all models.
ZyAIR B-500 Wireless Access Point User’s Guide unlicensed ISM (Industrial, Scientific and Medical) band. The third method is infrared technology, using very high frequencies, just below visible light in the electromagnetic spectrum to carry data. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless nodes or stations (STA), which is called a Basic Service Set (BSS).
ZyAIR B-500 Wireless Access Point User’s Guide The Extended Service Set (ESS) shown in the next figure consists of a series of overlapping BSSs (each containing an Access Point) connected together by means of a Distribution System (DS). Although the DS could be any type of network, it is almost invariably an Ethernet LAN. Mobile nodes can roam between access points and seamless campus-wide coverage is possible. Diagram D-2 ESS Provides Campus-Wide Coverage Wireless LAN and IEEE 802.
ZyAIR B-500 Wireless Access Point User’s Guide Appendix E Wireless LAN With IEEE 802.1x As wireless networks become popular for both portable computing and corporate networks, security is now a priority. Security Flaws with IEEE 802.11 Wireless networks based on the original IEEE 802.11 have a poor reputation for safety. The IEEE 802.11b wireless access standard, first published in 1999, was based on the MAC address.
ZyAIR B-500 Wireless Access Point User’s Guide RADIUS Server Authentication Sequence The following figure depicts a typical wireless network with a remote RADIUS server for user authentication using EAPOL (EAP Over LAN). Client computer access authorized. Client computer access not authorized. Diagram E-1 Sequences for EAP MD5–Challenge Authentication E-2 Wireless LAN with IEEE 802.
ZyAIR B-500 Wireless Access Point User’s Guide Appendix F Types of EAP Authentication This appendix discusses the four popular EAP authentication types: EAP-MD5, EAP-TLS, EAP-TTLS and PEAP. The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station.
ZyAIR B-500 Wireless Access Point User’s Guide hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5 and EAPMSCHAPv2, for client authentication. For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, simple user name and password pair is more practical. The following table is a comparison of the features of four authentication types.
ZyAIR B-500 Wireless Access Point User’s Guide Appendix G IP Subnetting IP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1. IP addresses are categorized into different classes. The class of an address depends on the value of its first octet.
ZyAIR B-500 Wireless Access Point User’s Guide A class “A” address (24 host bits) can have 224 –2 hosts (approximately 16 million hosts). Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B” address has a valid range of 128 to 191.
ZyAIR B-500 Wireless Access Point User’s Guide sequence of ones beginning from the left most bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits. Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet.
ZyAIR B-500 Wireless Access Point User’s Guide Divide the network 192.168.1.0 into two separate subnets by converting one of the host ID bits of the IP address to a network number bit. The “borrowed” host ID bit can be either “0” or “1” thus giving two subnets; 192.168.1.0 with mask 255.255.255.128 and 192.168.1.128 with mask 255.255.255.128. In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits.
ZyAIR B-500 Wireless Access Point User’s Guide to an actual host for the first subnet is 192.168.1.1 and the highest is 192.168.1.126. Similarly the host ID range for the second subnet is 192.168.1.129 to 192.168.1.254. Example: Four Subnets The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00, 01, 10 and 11.
